Home Broadband contract with Three for 1 year and 7 months. Excellent speeds and no disconnection ever. I was so pleased with this system. However just over two weeks ago the modem/router started disconnecting from the local 5G network several times each day with reduced download speeds compared to previously. Part of my home security system is out of action without a broadband connection and part of it ironically relies on cellular backup. Three support, via two chats, assured me that a new SIM card would sort everything out. Received the card via post and installed it nearly a week ago. There has been no change and the modem/router disconnects several times each day as previously. Could someone advise why Three is apparently unaware of what the issue is and how to solve it? I do not wish to spend the rest of my life in an everlasting loop of turning off/on a faulty item. I am only a few months away from the end of my contract. My wife and I both have Three mobile contracts and are content with the service. The mobile data download speed from our phones, in the same location as the modem/router is five times faster. I hope there is a team working on a solution to this problem. A moderator pointed out that customers with problems are more likely to be posting on these forums. Does that mean that most customers are content and have no issues. If that is the case then the diagnosis and a solution should be easier to find surely?
